3 * WARNING: Future backward-incompatibilities!
5 - Automake 1.14 will likely require Autoconf 2.70 or later (which is
6 still unreleased at the moment of writing, but is planned to be
7 released before Automake 1.14 is).
9 - Automake 1.14 will likely drop support for the long-deprecated
10 'configure.in' name for the Autoconf input file. You are advised
11 to use the recommended name 'configure.ac' instead.
13 - The long-obsolete (since automake 1.10) AM_PROG_MKDIR m4 macro will
14 be removed in Automake 1.14. The $(mkdir_p) make variable and the
15 @mkdir_p@ substitution will still remain available (as aliases of
16 $(MKDIR_P)) for the moment, for better backward compatibility; but
17 you are advised to stop using ASAP.
19 - The ACLOCAL_AMFLAGS special make variable will be fully deprecated
20 in Automake 1.14 (where it will raise warnings in the "obsolete"
21 category). You are advised to start relying on the new Automake
22 support for AC_CONFIG_MACRO_DIRS instead (which is introduced with
23 this release; see below for more information).
25 - Support for IRIX and the SGI C/C++ compilers will be removed in
26 Automake 1.14: they have seen their last release in 2006, and SGI
27 is expected to retire support from them in December 2013; see
28 <http://www.sgi.com/services/support/irix_mips_support.html> for
31 - Support for the long-deprecated INCLUDES variable will be removed
32 altogether in Automake 1.14. The AM_CPPFLAGS variable should be
35 - Automake-provided scripts and makefile recipes might (finally!)
36 start assuming a POSIX shell in Automake 1.14.
38 - Starting from Automake 1.14, third-party m4 files located in the
39 system-wide aclocal directory, as well as in any directory listed
40 in the ACLOCAL_PATH environment variable, will take precedence
41 over "built-in" Automake macros. For example (assuming Automake
42 is installed in the /usr/local hierarchy), a definition of the
43 AM_PROG_VALAC macro found in '/usr/local/share/aclocal/my-vala.m4'
44 should take precedence over the same-named automake-provided macro
45 (defined in '/usr/local/share/aclocal-1.14/vala.m4').
47 * Version requirements:
49 - Autoconf 2.65 or greater is now required.
51 - The rules to build PDF and DVI output from Texinfo input now
52 require Texinfo 4.9 or later.
56 - Support for the "Cygnus-style" trees (once enabled by the 'cygnus'
57 option) has been removed. See discussion about automake bug#11034
58 for more background: <debbugs.gnu.org/11034>.
60 - The deprecated aclocal option '--acdir' has been removed. You
61 should use the options '--automake-acdir' and '--system-acdir'
62 instead (which have been introduced in Automake 1.11.2).
64 - The following long-obsolete m4 macros have been removed:
66 AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
67 fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
68 fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
69 AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
70 ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
71 jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
72 ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
73 gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
74 fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
75 of the now-removed automatic de-ANSI-fication
78 - All the "old alias" macros in 'm4/obsolete.m4' have been removed.
80 - Use of the long-deprecated two- and three-arguments invocation forms
81 of the AM_INIT_AUTOMAKE is no longer documented. It's still supported
82 though (albeit with a warning in the 'obsolete' category), to cater
83 for people who want to define the version number for their package
84 dynamically (e.g., from the current VCS revision). We'll have to
85 continue this support until Autoconf itself is fixed to allow better
86 support for such dynamic version numbers.
88 * Elisp byte-compilation:
90 - The byte compilation of '.el' files into '.elc' files is now done
91 with a suffix rule. This has simplified the compilation process, and
92 more importantly made it less brittle. The downside is that emacs is
93 now invoked once for each '.el' files, which cause some noticeable
94 slowdowns. These should however be mitigated on multicore machines
95 (which are becoming the norm today) if concurrent make ("make -j")
98 - Elisp files placed in a subdirectory are now byte-compiled to '.elc'
99 files in the same subdirectory; for example, byte-compiling of file
100 'sub/foo.el' file will result in 'sub/foo.elc' rather than in
101 'foo.elc'. This behaviour is backward-incompatible with older
102 Automake versions, but it is more natural and more sane. See also
105 - The Emacs invocation performing byte-compilation of '.el' files honors
106 the $(AM_ELCFLAGS) and $(ELCFLAGS) variables; as typical, the former
107 one is developer-reserved and the latter one user-reserved.
109 - The 'elisp-comp' script, once provided by Automake, has been rendered
110 obsoleted by the just-described changes, and thus removed.
112 * Changes to Automake-generated testsuite harnesses:
114 - The parallel testsuite harness (previously only enabled by the
115 'parallel-tests' option) is the default one; the older serial
116 testsuite harness will still be available through the use of the
117 'serial-tests' option (introduced in Automake 1.12).
119 - The 'color-tests' option is now unconditionally activated by default.
120 In particular, this means that testsuite output is now colorized by
121 default if the attached terminal seems to support ANSI escapes, and
122 that the user can force output colorization by setting the variable
123 AM_COLOR_TESTS to "always". The 'color-tests' is still recognized
124 for backward-compatibility, although it's a handled as a no-op now.
126 * Silent rules support:
128 - Support for silent rules is now always active in Automake-generated
129 Makefiles. So, although the verbose output is still the default,
130 the user can now always use "./configure --enable-silent-rules" or
131 "make V=0" to enable quieter output in the package he's building.
133 - The 'silent-rules' option has now become a no-op, preserved for
134 backward-compatibility only. In particular, its use no longer
135 disables the warnings in the 'portability-recursive' category.
139 - The rules to build PDF and DVI files from Texinfo input now require
140 Texinfo 4.9 or later.
142 - The rules to build PDF and DVI files from Texinfo input now use the
143 '--build-dir' option, to keep the auxiliary files used by texi2dvi
144 and texi2pdf around without cluttering the build directory, and to
145 make it possible to run the "dvi" and "pdf" recipes in parallel.
147 * Automatic remake rules and 'missing' script:
149 - The 'missing' script no longer tries to update the timestamp of
150 out-of-date files that require a maintainer-specific tool to be
151 remade, in case the user lacks such a tool (or has a too-old version
152 of it). It just give a useful warning, and in some cases also a tip
153 about how to obtain such a tool.
155 - The missing script has thus become useless as a (poor) way to work
156 around the sketched-timestamps issues that can happen for projects
157 that keep generated files committed in their VCS repository. Such
158 projects are now encouraged to write a custom "fix-timestamps.sh"
159 script to avoid such issues; a simple example is provided in the
160 "CVS and generated files" chapter of the automake manual.
164 - The user can now define his own recursive targets that recurse
165 in the directories specified in $(SUBDIRS). This can be done by
166 specifying the name of such targets in invocations of the new
167 'AM_EXTRA_RECURSIVE_TARGETS' m4 macro.
171 - Any failure in the recipe of the "tags", "ctags", "cscope" or
172 "cscopelist" targets in a subdirectory is now propagated to the
173 top-level make invocation.
175 - Tags are correctly computed also for files in _SOURCES variables that
176 only list files with non-standard suffixes (see automake bug#12372).
178 * Improvements to aclocal and related rebuilds rules:
180 - Autoconf-provided macros AC_CONFIG_MACRO_DIR and AC_CONFIG_MACRO_DIRS
181 are now traced by aclocal, and can be used to declare the local m4
182 include directories. Formerly, one had to specify it with an explicit
183 '-I' option to the 'aclocal' invocation.
185 - The special make variable ACLOCAL_AMFLAGS is deprecated; future
186 Automake versions will warn about its use, and later version will
187 remove support for it altogether.
189 * The depcomp script:
191 - Dropped support for libtool 1.4.
193 - Various internal refactorings. They should cause no visible change,
194 but the chance for regression is there anyway, so please report any
195 unexpected or suspicious behaviour.
197 - Support for pre-8.0 versions of the Intel C Compiler has been dropped.
198 This should cause no problem, since icc 8.0 has been released in
199 December 2003 -- almost nine years ago.
201 - Support for tcc (the Tiny C Compiler) has been improved, and is now
202 handled through a dedicated 'tcc' mode.
204 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
206 Bugs fixed in 1.12.6:
208 * Python-related bugs:
210 - The default installation location for python modules has been improved
211 for Python 3 on Debian and Ubuntu systems, changing from:
213 ${prefix}/lib/python3/dist-packages
217 ${prefix}/lib/python3.x/site-packages
219 This change should ensure modules installed using the default ${prefix}
220 "/usr/local" are found by default by system python 3.x installations.
221 See automake bug#10227.
223 - Python byte-compilation supports the new layout mandated by PEP-3147,
224 with its __pycache__ directory (automake bug#8847).
226 * Build system issues:
228 - The maintainer rebuild rules for Makefiles and aclocal.m4 in
229 Automake's own build system works correctly again (bug introduced
234 - The Vala-related tests has been changed to adjust to the removal of
235 the 'posix' profile in the valac compiler. See automake bug#12934
238 - Some spurious testsuite failures related to older tools and systems
241 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
247 - The AM_PROG_VALAC macro has been enhanced to takes two further
248 optional arguments; it's signature now being
250 AM_PROG_VALAC([MINIMUM-VERSION], [ACTION-IF-FOUND],
251 [ACTION-IF-NOT-FOUND])
253 - By default, AM_PROG_VALAC no longer aborts the configure invocation
254 if the Vala compiler found is too old, but simply prints a warning
255 messages (as it did when the Vala compiler was not found). This
256 should avoid unnecessary difficulties for end users that just want
257 to compile the unmodified, distributed Vala-generated C sources,
258 but happens to have an old Vala compiler in their PATH. This fixes
261 - If no proper Vala compiler is found at configure runtime, AM_PROG_VALAC
262 will set the AC_SUBST'd variable 'VALAC' to 'valac' rather than to ':'.
263 This is a better default, because with it a triggered makefile rule
264 invoking a Vala compilation will clearly fail with an informative error
265 message like "valac: command not found", rather than silently, with
266 the error possibly going unnoticed or triggering harder-to-diagnose
267 fallout failures in later steps.
269 * Miscellaneous changes:
271 - automake and aclocal no longer honours the 'perllibdir' environment
272 variable. That had always been intended only as an hack required in
273 the testsuite, not meant for any use beyond that.
275 Bugs fixed in 1.12.5:
277 * Long-standing bugs:
279 - Automake no longer generates spurious remake rules invoking autoheader
280 to regenerate the template corresponding to header files specified after
281 the first one in AC_CONFIG_HEADERS (automake bug#12495).
283 - When wrapping Microsoft tools, the 'compile' script falls back to
284 finding classic 'libname.a' style libraries when 'name.lib' and
285 'name.dll.lib' aren't available.
287 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
291 * Warnings and deprecations:
293 - Warnings in the 'obsolete' category are enabled by default both in
294 automake and aclocal.
296 * Miscellaneous changes:
298 - Some testsuite weaknesses and spurious failures have been fixed.
300 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
304 * Miscellaneous changes:
306 - The '.m4' files provided by Automake no longer define serial numbers.
307 This should cause no difference in the behaviour of aclocal though.
309 - Some testsuite weaknesses and spurious failures have been fixed.
311 - There is initial support for automatic dependency tracking with the
312 Portland Group C/C++ compilers, thanks to the new new depmode 'pgcc'.
314 Bugs fixed in 1.12.3:
316 * Long-standing bugs:
318 - Instead of renaming only self-references of files (typically for
319 #lines), ylwrap now also renames references to the other generated
320 files. This fixes support for GLR and C++ parsers from Bison (PR
321 automake/491 and automake bug#7648): 'parser.c' now properly
322 #includes 'parser.h' instead of 'y.tab.h'.
324 - Generated files unknown to ylwrap are now preserved. This fixes
325 C++ support for Bison (automake bug#7648): location.hh and the
326 like are no longer discarded.
328 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
332 * Warnings and deprecations:
334 - Automake now issues a warning (in the 'portability' category) if
335 'configure.in' is used instead of 'configure.ac' as the Autoconf
336 input file. Such a warning will also be present in the next
337 Autoconf version (2.70).
341 - Recursive cleaning rules descends into the $(SUBDIRS) in the natural
342 order (as done by the other recursive rules), rather than in the
343 inverse order. They used to do that in order to work a round a
344 limitation in an older implementation of the automatic dependency
345 tracking support, but that limitation had been lifted years ago
346 already, when the automatic dependency tracking based on side-effects
347 of compilation had been introduced.
349 - Cleaning rules for compiled objects (both "plain" and libtool) work
350 better when subdir objects are involved, not triggering a distinct
351 'rm' invocation for each such object. They do so by removing *any*
352 compiled object file that is in the same directory of a subdir
353 object. See automake bug#10697.
355 * Silent rules support:
357 - A new predefined $(AM_V_P) make variable is provided; it expands
358 to a shell conditional that can be used in recipes to know whether
359 make is being run in silent or verbose mode.
361 Bugs fixed in 1.12.2:
363 * SECURITY VULNERABILITIES!
365 - The 'distcheck' recipe no longer grants temporary world-write
366 permissions on the extracted distdir. Even if such rights were
367 only granted for a vanishingly small time window, the implied
368 race condition proved to be enough to allow a local attacker
369 to run arbitrary code with the privileges of the user running
370 "make distcheck". This is CVE-2012-3386.
372 * Long-standing bugs:
374 - The "recheck" targets behaves better in the face of build failures
375 related to previously failed tests. For example, if a test is a
376 compiled program that must be rerun by "make recheck", and its
377 compilation fails, it will still be rerun by further "make recheck"
378 invocations. See automake bug#11791.
380 * Bugs introduced by 1.12.1:
382 - Automake provides once again the '$(mkdir_p)' make variable and the
383 '@mkdir_p@' substitution (both as simple aliases for '$(MKDIR_P)'),
384 for better backward-compatibility.
386 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
390 * New supported languages:
392 - Support for Objective C++ has been added; it should work similarly to
393 the support for Objective C.
395 * Deprecated obsolescent features:
397 - Use of the long-deprecated two- and three-arguments invocation forms
398 of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
399 category. Starting from some future major Automake release (likely
400 post-1.13), such usages will no longer be allowed.
402 - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
403 now deprecated (its use triggers a warning in the 'obsolete' category).
404 It will be removed in the next major Automake release (1.13).
406 - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
407 variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
408 m4 macro are deprecated, eliciting a warning in the 'obsolete'
411 * Miscellaneous changes:
413 - The Automake test cases now require a proper POSIX-conforming shell.
414 Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) will no longer
415 be accepted. In most cases, the user shouldn't have to specify such
416 POSIX shell explicitly, since it will be looked up at configure time.
417 Still, when this lookup fails, or when the user wants to override its
418 conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be used (pointing
419 to the shell that will be used to run the Automake test cases).
421 Bugs fixed in 1.12.1:
423 * Bugs introduced by 1.12:
425 - Several weaknesses in Automake's own build system and test suite
428 * Bugs introduced by 1.11.3:
430 - When given non-option arguments, aclocal rejects them, instead of
431 silently ignoring them.
433 * Long-standing bugs:
435 - When the 'color-tests' option is in use, forcing of colored testsuite
436 output through "AM_COLOR_TESTS=always" works even if the terminal is
437 a non-ANSI one, i.e., if the TERM environment variable has a value of
440 - Several inefficiencies and poor performances in the implementation
441 of the parallel-tests 'check' and 'recheck' targets have been fixed.
443 - The post-processing of output "#line" directives done the ylwrap
444 script is more faithful w.r.t. files in a subdirectory; for example,
445 if the processed file is "src/grammar.y", ylwrap will correctly
446 produce directives like:
447 #line 7 "src/grammar.y"
452 * Bugs with new Perl versions:
454 - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
456 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
460 * Obsolete features removed:
462 - The never documented nor truly used script 'acinstall' has been
465 - Support for automatic de-ANSI-fication has been removed.
467 - The support for the "obscure" multilib feature has been removed
468 from Automake core (but remains available in the 'contrib/'
469 directory of the Automake distribution).
471 - Support for ".log -> .html" conversion and the check-html and
472 recheck-html targets has been removed from Automake core (but
473 remains available in the 'contrib/' directory of the Automake
476 - The deprecated 'lzma' compression format for distribution archives
477 has been removed, in favor of 'xz' and 'lzip'.
479 - The obsolete AM_WITH_REGEX macro has been removed.
481 - The long-deprecated options '--output-dir', '--Werror' and
482 '--Wno-error' have been removed.
484 - The chapter on the history of Automake has been moved out of the
485 reference manual, into a new dedicated Texinfo file.
489 - New 'cscope' target to build a cscope database for the source tree.
491 * Changes to Automake-generated testsuite harnesses:
493 - The new automake option 'serial-tests' has been introduced. It can
494 be used to explicitly instruct automake to use the older serial
495 testsuite harness. This is still the default at the moment, but it
496 might change in future versions.
498 - The 'recheck' target (provided by the parallel testsuite harness) now
499 depends on the 'all' target. This allows for a better user-experience
500 in test-driven development. See automake bug#11252.
502 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
503 and unexpected or internal error, or a failure to set up the test case
504 scenario) have their outcome reported as an 'ERROR' now. Previous
505 versions of automake reported such an outcome as a 'FAIL' (the only
506 difference with normal failures being that hard errors were counted
507 as failures even when the test originating them was listed in
510 - The testsuite summary displayed by the parallel-test harness has a
511 completely new format, that always list the numbers of passed, failed,
512 xfailed, xpassed, skipped and errored tests, even when these numbers
513 are zero (but using smart coloring when the color-tests option is in
516 - The default testsuite driver offered by the 'parallel-tests' option is
517 now implemented (partly at least) with the help of automake-provided
518 auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
519 on code in the generated Makefile.in.
520 This has two noteworthy implications. The first one is that projects
521 using the 'parallel-tests' option should now either run automake with
522 the '--add-missing' option, or manually copy the 'test-driver' script
523 into their tree. The second, and more important, implication is that
524 now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
525 no longer be used to define a test runner, and the command specified
526 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
527 program or script. For example, this is still a valid usage (albeit
530 TESTS_ENVIRONMENT = \
531 if test -n '$(STRICT_TESTS)'; then \
532 maybe_errexit='-e'; \
536 LOG_COMPILER = $(SHELL) $$maybe_errexit
538 OTOH, this is no longer a valid usage:
540 TESTS_ENVIRONMENT = \
541 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
545 TESTS_ENVIRONMENT = \
546 run_with_perl_or_shell () \
548 if grep -q '^#!.*perl' $$1; then
554 LOG_COMPILER = run_with_perl_or_shell
556 - The package authors can now use customary testsuite drivers within
557 the framework provided by the 'parallel-tests' testsuite harness.
558 Consistently with the existing syntax, this can be done by defining
559 special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
561 - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
562 to redirect/define file descriptors used by the test scripts.
564 - The parallel-tests harness generates now, in addition the '.log' files
565 holding the output produced by the test scripts, a new set of '.trs'
566 files, holding "metadata" derived by the execution of the test scripts;
567 among such metadata are the outcomes of the test cases run by a script.
569 - Initial and still experimental support for the TAP test protocol is
572 * Changes to Yacc and Lex support:
574 - C source and header files derived from non-distributed Yacc and/or
575 Lex sources are now removed by a simple "make clean" (while they were
576 previously removed only by "make maintainer-clean").
578 - Slightly backward-incompatible change, relevant only for use of Yacc
579 with C++: the extensions of the header files produced by the Yacc
580 rules are now modelled after the extension of the corresponding
581 sources. For example, yacc files named "foo.y++" and "bar.yy" will
582 produce header files named "foo.h++" and "bar.hh" respectively, where
583 they would have previously produced header files named simply "foo.h"
584 and "bar.h". This change offers better compatibility with 'bison -o'.
586 * Miscellaneous changes:
588 - The AM_PROG_VALAC macro now causes configure to exit with status 77,
589 rather than 1, if the vala compiler found is too old.
591 - The build system of Automake itself now avoids the use of make
592 recursion as much as possible.
594 - Automake now prefers to quote 'like this' or "like this", rather
595 than `like this', in diagnostic message and generated Makefiles,
596 to accommodate the new GNU Coding Standards recommendations.
598 - Automake has a new option '--print-libdir' that prints the path of the
599 directory containing the Automake-provided scripts and data files.
601 - The 'dist' and 'dist-all' targets now can run compressors in parallel.
603 - The rules to create pdf, dvi and ps output from Texinfo files now
604 works better with modern 'texi2dvi' script, by explicitly passing
605 it the '--clean' option to ensure stray auxiliary files are not
606 left to clutter the build directory.
608 - Automake can now generate silenced rules for texinfo outputs.
610 - Some auxiliary files that are automatically distributed by Automake
611 (e.g., 'install-sh', or the 'depcomp' script for packages compiling
612 C sources) might now be listed in the DIST_COMMON variable in many
613 Makefile.in files, rather than in the top-level one.
615 - Messages of types warning or error from 'automake' and 'aclocal'
616 are now prefixed with the respective type, and presence of -Werror
619 - Automake's early configure-time sanity check now tries to avoid
620 sleeping for a second, which slowed down cached configure runs
621 noticeably. In that case, it will check back at the end of the
622 configure script to ensure that at least one second has passed, to
623 avoid time stamp issues with makefile rules rerunning autotools
626 - The warnings in the category 'extra-portability' are now enabled by
627 '-Wall'. In previous versions, one has to use '-Wextra-portability'
632 - Various minor bugfixes for recent or long-standing bugs.
634 * Bugs introduced by 1.11:
636 - The AM_COND_IF macro also works if the shell expression for the
637 conditional is no longer valid for the condition.
639 - The automake-provided parallel testsuite harness no longer fails
640 with BSD make used in parallel mode when there are test scripts in
641 a subdirectory, like in:
643 TESTS = sub/foo.test sub/bar.test
645 * Long-standing bugs:
647 - Automake's own build system finally have a real "installcheck" target.
649 - Vala-related cleanup rules are now more complete, and work better in
652 - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
653 now automatically distributed also if the directory of the auxiliary
654 files coincides with the top-level directory.
656 - Automake now detects the presence of the '-d' flag in the various
657 '*YFLAGS' variables even when their definitions involve indirections
658 through other variables, such as in:
660 AM_YFLAGS = $(foo_opts)
662 - Automake now complains if a '*YFLAGS' variable has any conditional
663 content, not only a conditional definition.
665 - Explicit enabling and/or disabling of Automake warning categories
666 through the '-W...' options now always takes precedence over the
667 implicit warning level implied by Automake strictness (foreign, gnu
668 or gnits), regardless of the order in which such strictness and
669 warning flags appear. For example, a setting like:
670 AUTOMAKE_OPTIONS = -Wall --foreign
671 will cause the warnings in category 'portability' to be enabled, even
672 if those warnings are by default disabled in 'foreign' strictness.
674 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
676 Bugs fixed in 1.11.5:
678 * Bugs introduced by 1.11.3:
680 - Vala files with '.vapi' extension are now recognized and handled
681 correctly again. See automake bug#11222.
683 - Vala support work again for projects that contain some program
684 built from '.vala' (and possibly '.c') sources and some other
685 program built from '.c' sources *only*. See automake bug#11229.
687 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
691 * Miscellaneous changes:
693 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
694 symbol index) modifiers as well as the "s" action, as the symbol index
695 is created unconditionally by Microsoft lib. Also, the "q" (quick)
696 action is now a synonym for "r" (replace). Also, the script has been
697 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
699 - When the 'compile' script is used to wrap MSVC, it now accepts an
700 optional space between the -I, -L and -l options and their respective
701 arguments, for better POSIX compliance.
703 - There is an initial, experimental support for automatic dependency
704 tracking with tcc (the Tiny C Compiler). Its associated depmode is
705 currently recognized as "icc" (but this and other details are likely
706 to change in future versions).
708 - Automatic dependency tracking now works also with the IBM XL C/C++
709 compilers, thanks to the new new depmode 'xlc'.
711 Bugs fixed in 1.11.4:
713 * Bugs introduced by 1.11.2:
715 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
716 no longer cause spurious failures upon "make install".
718 - The user can now instruct the 'uninstall-info' rule not to update
719 the '${infodir}/dir' file by exporting the environment variable
720 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
721 with how the 'install-info' rule operates since automake 1.11.2.
723 * Long-standing bugs:
725 - It is now possible for a foo_SOURCES variable to hold Vala sources
726 together with C header files, as well as with sources and headers for
727 other supported languages (e.g., C++). Previously, only mixing C and
728 Vala sources was supported.
730 - If "aclocal --install" is used, and the first directory specified with
731 '-I' is non-existent, aclocal will now create it before trying to copy
734 - An empty declaration of a "foo_PRIMARY" no longer cause the generated
735 install rules to create an empty $(foodir) directory; for example, if
736 Makefile.am contains something like:
740 pkglibexec_SCRIPTS += bar.sh
743 the $(pkglibexec) directory will not be created upon "make install".
745 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
749 * Miscellaneous changes:
751 - Automake's own build system is more silent by default, making use of
752 the 'silent-rules' option.
754 - The master copy of the 'gnupload' script is now maintained in gnulib,
757 - The 'missing' script no longer tries to wrap calls to 'tar'.
759 - "make dist" no longer wraps 'tar' invocations with the 'missing'
760 script. Similarly, the obsolescent variable '$(AMTAR)' (which you
761 shouldn't be using BTW ;-) no longer invokes the 'missing' script
762 to wrap tar, but simply invokes the 'tar' program itself.
764 - "make dist" can now create lzip-compressed tarballs.
766 - In the Automake info documentation, the Top node and the nodes about
767 the invocation of the automake and aclocal programs have been renamed;
768 now, calling "info automake" will open the Top node, while calling
769 "info automake-invocation" and "info aclocal-invocation" will access
770 the nodes about the invocation of respectively automake and aclocal.
772 - Automake is now distributed as a gzip-compressed and an xz-compressed
773 tarball. Previously, bzip2 was used instead of xz.
775 - The last relics of Python 1.5 support have been removed from the
776 AM_PATH_PYTHON macro.
778 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
779 and adds them to the normal list of dependencies, but without
780 overwriting the foo_DEPENDENCIES variable, which is normally computed
783 Bugs fixed in 1.11.3:
785 * Bugs introduced by 1.11.2:
787 - Automake now correctly recognizes the prefix/primary combination
788 'pkglibexec_SCRIPTS' as valid.
790 - The parallel-tests harness no longer trips on sed implementations
791 with stricter limits on the length of input lines (problem seen at
794 * Long-standing bugs:
796 - The "deleted header file problem" for *.am files is avoided by stub
797 rules. This allows 'make' to trigger a rerun of 'automake' also if
798 some previously needed '.am' file has been removed.
800 - The 'silent-rules' option now generates working makefiles even
801 for the uncommon 'make' implementations that do not support the
802 nested-variables extension to POSIX 2008. For such 'make'
803 implementations, whether a build is silent is determined at
804 configure time, and cannot be overridden at make time with
805 "make V=0" or "make V=1".
807 - Vala support now works better in VPATH setups.
809 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
813 * Changes to aclocal:
815 - The `--acdir' option is deprecated. Now you should use the new options
816 `--automake-acdir' and `--system-acdir' instead.
818 - The `ACLOCAL_PATH' environment variable is now interpreted as a
819 colon-separated list of additional directories to search after the
820 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
821 and before the system acdir (by default ${prefix}/share/aclocal).
823 * Miscellaneous changes:
825 - The Automake support for automatic de-ANSI-fication has been
826 deprecated. It will probably be removed in the next major Automake
829 - The `lzma' compression scheme and associated automake option `dist-lzma'
830 is obsoleted by `xz' and `dist-xz' due to upstream changes.
832 - You may adjust the compression options used in dist-xz and dist-bzip2.
833 The default is now merely -e for xz, but still -9 for bzip; you may
834 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
835 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
837 - The `compile' script now converts some options for MSVC for a better
838 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
840 - The py-compile script now accepts empty arguments passed to the options
841 `--destdir' and `--basedir', and complains about unrecognized options.
842 Moreover, a non-option argument or a special `--' argument terminates
845 - A developer that needs to pass specific flags to configure at "make
846 distcheck" time can now, and indeed is advised to, do so by defining
847 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
848 instead of the old DISTCHECK_CONFIGURE_FLAGS.
849 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
850 user; still, the old Makefile.am files that used to define it will
851 still continue to work as before.
853 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
854 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
855 This new macro is required for LIBRARIES and LTLIBRARIES when automake
856 is run with -Wextra-portability and -Werror.
858 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
859 file generated by automake-provided rules by defining the special make
860 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
862 - The `install-info' rule can now be instructed not to create/update
863 the `${infodir}/dir' file, by exporting the new environment variable
864 `AM_UPDATE_INFO_DIR' to the value "no".
866 Bugs fixed in 1.11.2:
868 * Bugs introduced by 1.11:
870 - The parallel-tests driver no longer produces erroneous results with
871 Tru64/OSF 5.1 sh upon unreadable log files.
873 - The `parallel-tests' test driver does not report spurious successes
874 when used with concurrent FreeBSD make (e.g., "make check -j3").
876 - When the parallel-tests driver is in use, automake now explicitly
877 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
878 instead of issuing confusing and apparently unrelated error messages
879 (e.g., "non-POSIX variable name", "bad characters in variable name",
880 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
881 silently producing broken `Makefile.in' files.
883 - The `silent-rules' option now truly silences all compile rules, even
884 when dependency tracking is disabled. Also, when `silent-rules' is
885 not used, `make' output no longer contains spurious backslash-only
886 lines, thus once again matching what Automake did before 1.11.
888 - The AM_COND_IF macro also works if the shell expression for the
889 conditional is no longer valid for the condition.
891 * Long-standing bugs:
893 - The order of Yacc and Lex flags is fixed to be consistent with other
894 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
895 $(LFLAGS), so that the user variables override the developer variables.
897 - "make distcheck" now correctly complains also when "make uninstall"
898 leaves one and only one file installed in $(prefix).
900 - A "make uninstall" issued before a "make install", or after a mere
901 "make install-data" or a mere "make install-exec" does not spuriously
904 - Automake now warns about more primary/directory invalid combinations,
905 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
907 - Rules generated by Automake now try harder to not change any files when
908 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
909 Yacc source files and the rule to update config.h.
911 - Several scripts and the parallel-tests testsuite driver now exit with
912 the right exit status upon receiving a signal.
914 - A per-Makefile.am setting of -Werror does not erroneously carry over
915 to the handling of other Makefile.am files.
917 - The code for automatic dependency tracking works around a Solaris
918 make bug triggered by sources containing repeated slashes when the
919 `subdir-objects' option was used.
921 - The makedepend and hp depmodes now work better with VPATH builds.
923 - Java sources specified with check_JAVA are no longer compiled for
924 "make all", but only for "make check".
926 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
927 and error out if `javadir' is undefined, instead of silently producing
928 a broken Makefile.in.
930 - aclocal and automake now honour the configure-time definitions of
931 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
933 - The `install-info' recipe no longer tries to guess whether the
934 `install-info' program is from Debian or from GNU, and adaptively
935 change its behaviour; this has proven to be frail and easy to
938 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
940 Bugs fixed in 1.11.1:
942 - Lots of minor bugfixes.
944 * Bugs introduced by 1.11:
946 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
947 trailing white space in the test list (`TESTS = foo $(EMPTY)').
949 * Long standing bugs:
951 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
952 even if the `--prefix' argument pointed outside of a system directory.
953 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
954 `get_python_lib' function if it points outside the configured prefix,
955 unless the `--prefix' argument was either `/usr' or below `/System'.
957 - The testsuite does not try to change the mode of `ltmain.sh' files from
958 a Libtool installation (symlinked to test directories) any more.
960 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
961 tools are preferred in a cross-compile setup.
963 - The distribution is tarred up with mode 755 now by the `dist*' targets.
964 This fixes a race condition where untrusted users could modify files
965 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
966 build directory was world-searchable. This is CVE-2009-4029.
968 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
972 * Version requirements:
974 - Autoconf 2.62 or greater is required.
976 * Changes to aclocal:
978 - The autoconf version check implemented by aclocal in aclocal.m4
979 (and new in Automake 1.10) is degraded to a warning. This helps
980 in the common case where the Autoconf versions used are compatible.
982 * Changes to automake:
984 - The automake program can run multiple threads for creating most
985 Makefile.in files concurrently, if at least Perl 5.7.2 is available
986 with interpreter-based threads enabled. Set the environment variable
987 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
988 enable this experimental feature.
990 * Changes to Libtool support:
992 - Libtool generic flags are now passed to the install and uninstall
995 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
996 config.lt is removed correctly now.
1000 - subdir-object mode works now with Fortran (F77, FC, preprocessed
1001 Fortran, and Ratfor).
1003 - For files with extension .f90, .f95, .f03, or .f08, the flag
1004 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
1006 - Files with extension .sx are also treated as preprocessed assembler.
1008 - The default source file extension (.c) can be overridden with
1009 AM_DEFAULT_SOURCE_EXT now.
1011 - Python 3.0 is supported now, Python releases prior to 2.0 are no
1014 - AM_PATH_PYTHON honors python's idea about the site directory.
1016 - There is initial support for the Vala programming language, when using
1017 Vala 0.7.0 or later.
1019 * Miscellaneous changes:
1021 - Automake development is done in a git repository on Savannah now, see
1023 http://git.sv.gnu.org/gitweb/?p=automake.git
1025 A read-only CVS mirror is provided at
1027 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
1028 checkout -d automake HEAD
1030 - "make dist" can now create xz-compressed tarballs,
1031 as well as (deprecated?) lzma-compressed tarballs.
1033 - `automake --add-missing' will by default install the GPLv3 file as
1034 COPYING if it is missing. It will also warn that the license file
1035 should be added to source control. Note that Automake will never
1036 overwrite an existing COPYING file, even when the `--force-missing'
1039 - The manual is now distributed under the terms of the GNU FDL 1.3.
1041 - Automake ships and installs man pages for automake and aclocal now.
1043 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
1045 - install-sh supports -C, which does not update the installed file
1046 (and its time stamps) if the contents did not change.
1048 - The `gnupload' script has been revamped.
1050 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
1052 - The targets `install' and `uninstall' are more efficient now, in that
1053 for example multiple files from one Automake variable such as
1054 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
1055 invocation if they do not have to be renamed.
1057 Both install and uninstall may sometimes enter (`cd' into) the target
1058 installation directory now, when no build-local scripts are used.
1060 Both install and uninstall do not fail anymore but do nothing if an
1061 installation directory variable like `bindir' is set to the empty string.
1063 For built-in rules, `make install' now fails reliably if installation
1064 of a file failed. Conversely, `make uninstall' even succeeds when
1065 issued multiple times.
1067 These changes may need some adjustments from users: For example,
1068 some `install' programs refuse to install multiple copies of the
1069 same file in one invocation, so you may need to remove duplicate
1070 entries from file lists.
1072 Also, within one set of files, say, nobase_data_DATA, the order of
1073 installation may be changed, or even unstable among different hosts,
1074 due to the use of associative arrays in awk. The increased use of
1075 awk matches a similar move in Autoconf to provide for better scaling.
1077 Further, most undocumented per-rule install command variables such as
1078 binSCRIPT_INSTALL have been removed because they are not needed any
1079 more. Packages which use them should be using the appropriate one of
1080 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
1081 counterpart, depending on the type of files and the need for automatic
1082 target directory creation.
1084 - The "deleted header file problem" for *.m4 files is avoided by
1085 stub rules. This allows `make' to trigger a rerun of `aclocal'
1086 also if some previously needed macro file has been removed.
1088 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
1089 an otherwise up to date tree.
1091 - The `color-tests' option causes colored test result output on terminals.
1093 - The `parallel-tests' option enables a new test driver that allows for
1094 parallel test execution, inter-test dependencies, lazy test execution
1095 for unit-testing, re-testing only failed tests, and formatted result output
1096 as RST (reStructuredText) and HTML. Enabling this option may require some
1097 changes to your test suite setup; see the manual for details.
1099 - The `silent-rules' option enables Linux kernel-style silent build output.
1100 This option requires the widely supported but non-POSIX `make' feature
1101 of recursive variable expansion, so do not use it if your package needs
1102 to build with `make' implementations that do not support it.
1104 To enable less verbose build output, the developer has to use the Automake
1105 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
1106 macro. The user may then set the default verbosity by passing the
1107 `--enable-silent-rules' option to `configure'. At `make' run time, this
1108 default may be overridden using `make V=0' for less verbose, and `make V=1'
1109 for backward-compatible verbose output.
1111 - New prefix `notrans_' for manpages which should not be transformed
1112 by --program-transform.
1114 - New macro AM_COND_IF for conditional evaluation and conditional
1117 - For AC_CONFIG_LINKS, if source and destination are equal, do not
1118 remove the file in a non-VPATH build. Such setups work with Autoconf
1121 - AM_MAINTAINER_MODE now allows for an optional argument specifying
1122 the default setting.
1124 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
1125 useful especially for multi-line values.
1127 - Automake's early configure-time sanity check now diagnoses an
1128 unsafe absolute source directory name and makes configure fail.
1130 - The Automake macros and rules cope better with whitespace in the
1131 current directory name, as long as the relative path to `configure'
1132 does not contain whitespace. To this end, the values of `$(MISSING)'
1133 and `$(install_sh)' may contain suitable quoting, and their expansion
1134 might need `eval'uation if used outside of a makefile. These
1135 undocumented variables may be used in several documented macros such
1136 as $(AUTOCONF) or $(MAKEINFO).
1140 * Long-standing bugs:
1142 - Fix aix dependency tracking for libtool objects.
1144 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
1145 unnecessary use of the `compile' script.
1147 - For nobase_*_LTLIBRARIES with nonempty directory components, the
1148 correct `-rpath' argument is used now.
1150 - `config.status --file=Makefile depfiles' now also works with the
1151 extra quoting used internally by Autoconf 2.62 and newer
1152 (it used to work only without the `--file=' bit).
1154 - The `missing' script works better with versioned tool names.
1156 - Semantics for `missing help2man' have been revamped:
1158 Previously, if `help2man' was not present, `missing help2man' would have
1159 the following semantics: if some man page was out of date but present, then
1160 a warning would be printed, but the exit status was 0. If the man page was
1161 not present at all, then `missing' would create a replacement man page
1162 containing an error message, and exit with a status of 2. This does not play
1163 well with `make': the next run will see this particular man page as being up
1164 to date, and will only error out on the next generated man page, if any;
1165 repeat until all pages are done. This was not desirable.
1167 These are the new semantics: if some man page is not present, and help2man
1168 is not either, then `missing' will warn and generate the replacement page
1169 containing the error message, but exit successfully. However, `make dist'
1170 will ensure that no such bogus man pages are packaged into a tarball.
1172 - Targets provided by automake behave better with `make -n', in that they
1173 take care not to create files.
1175 - `config.status Makefile... depfiles' works fine again in the presence of
1176 disabled dependency tracking.
1178 - The default no-op recursive rules for these targets also work with BSD make
1179 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
1181 - `make distcheck' works also when both a directory and some file below it
1182 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
1184 - Texinfo dvi, ps, pdf, and html output files are not removed upon
1185 `make mostlyclean' any more; only the LaTeX by-products are.
1187 - Renamed objects also work with the `subdir-objects' option and
1188 source file languages which Automake does not know itself.
1190 - `automake' now correctly complains about variable assignments which are
1191 preceded by a comment, extend over multiple lines with backslash-escaped
1192 newlines, and end in a comment sign. Previous versions would silently
1193 and wrongly ignore such assignments completely.
1195 * Bugs introduced by 1.10:
1197 - Fix output of dummy dependency files in presence of post-processed
1198 Makefile.in's again, but also cope with long lines.
1200 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
1201 that have been declared as programs in the same Makefile.
1202 This is for consistency with the analogous change to TESTS in 1.10.
1204 - Fix order of standard includes to again be `-I. -I$(srcdir)',
1205 followed by directories containing config headers.
1207 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1211 * Version requirements:
1213 - Autoconf 2.60 or greater is required.
1215 - Perl 5.6 or greater is required.
1217 * Changes to aclocal:
1219 - aclocal now also supports -Wmumble and -Wno-mumble options.
1221 - `dirlist' entries (for the aclocal search path) may use shell
1222 wildcards such as `*', `?', or `[...]'.
1224 - aclocal supports an --install option that will cause system-wide
1225 third-party macros to be installed in the local directory
1226 specified with the first -I flag. This option also uses #serial
1227 lines in M4 files to upgrade local macros.
1229 The new aclocal options --dry-run and --diff help to review changes
1230 before they are installed.
1232 - aclocal now outputs an autoconf version check in aclocal.m4 in
1233 projects using automake.
1235 For a few years, automake and aclocal have been calling autoconf
1236 (or its underlying engine autom4te) to accurately retrieve the
1237 data they need from configure.ac and its siblings. Doing so can
1238 only work if all autotools use the same version of autoconf. For
1239 instance a Makefile.in generated by automake for one version of
1240 autoconf may stop working if configure is regenerated with another
1241 version of autoconf, and vice versa.
1243 This new version check ensures that the whole build system has
1244 been generated using the same autoconf version.
1246 * Support for new Autoconf macros:
1248 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
1250 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
1251 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
1252 in different directories. However, only one instance of such a
1253 library objects directory is supported.
1255 * Change to Libtool support:
1257 - Libtool generic flags (those that go before the --mode=MODE option)
1258 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
1260 * Yacc and Lex changes:
1262 - The rebuild rules for distributed Yacc and Lex output will avoid
1263 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
1266 - ylwrap is now always used for lex and yacc source files,
1267 regardless of whether there is more than one source per directory.
1269 * Languages changes:
1271 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
1272 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
1273 tracking, unlike non-preprocessed assembler (*.s).
1275 - subdir-object mode works now with Assembler. Automake assumes
1276 that the compiler understands `-c -o'.
1278 - Preprocessed assembler (*.S) compilation now also honors
1279 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
1281 - Improved support for Objective C:
1282 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
1283 - A new section of the manual documents the support.
1285 - New support for Unified Parallel C:
1286 - AM_PROG_UPC looks for a UPC compiler.
1287 - A new section of the manual documents the support.
1289 - Per-target flags are now correctly handled in link rules.
1291 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
1292 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
1293 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
1294 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
1296 The fix for compiler flags (i.e., using maude_CFLAGS instead of
1297 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
1298 is expected to work (and actually works during compilation).
1300 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
1301 "in addition to" breaks backward compatibility with older versions.
1302 If your package used both variables, as in
1304 AM_LDFLAGS = common flags
1305 bin_PROGRAMS = a b c
1306 a_LDFLAGS = more flags
1309 and assumed *_LDFLAGS would sum up, you should rewrite it as
1311 AM_LDFLAGS = common flags
1312 bin_PROGRAMS = a b c
1313 a_LDFLAGS = $(AM_LDFLAGS) more flags
1316 This new behavior of *_LDFLAGS is more coherent with other
1317 per-target variables, and the way *_LDFLAGS variables were
1318 considered internally.
1320 * New installation targets:
1322 - New targets mandated by GNU Coding Standards:
1327 By default they will only install Texinfo manuals.
1328 You can customize them with *-local variants:
1334 - The undocumented recursive target `uninstall-info' no longer exists.
1335 (`uninstall' is in charge of removing all possible documentation
1336 flavors, including optional formats such as dvi, ps, or info even
1337 when `no-installinfo' is used.)
1339 * Miscellaneous changes:
1341 - Automake no longer complains if input files for AC_CONFIG_FILES
1342 are specified using shell variables.
1344 - clean, distribution, or rebuild rules are normally disabled for
1345 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
1346 AC_CONFIG_LINK specified using shell variables. However, if these
1347 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
1348 be able to output rules anyway.
1349 (See the Automake documentation for AC_CONFIG_FILES.)
1351 - $(EXEEXT) is automatically appended to filenames of TESTS
1352 that have been declared as programs in the same Makefile.
1353 This is mostly useful when some check_PROGRAMS are listed in TESTS.
1355 - `-Wportability' has finally been turned on by default for `gnu' and
1356 `gnits' strictness. This means, automake will complain about %-rules
1357 or $(GNU Make functions) unless you switch to `foreign' strictness or
1358 use `-Wno-portability'.
1360 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
1361 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
1362 $(mkdir_p) variable is still defined (to the same value as
1363 $(MKDIR_P)) but should be considered obsolete. If you are using
1364 $(mkdir_p) in some of your rules, please plan to update them to
1365 $(MKDIR_P) at some point.
1367 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
1368 They still work in this release, but may be withdrawn in a future one.
1370 - Inline compilation rules for gcc3-style dependency tracking are
1373 - Automake installs a "Hello World!" example package in $(docdir).
1374 This example is used throughout the new "Autotools Introduction"
1375 chapter of the manual.
1377 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1381 * Makefile.in bloat reduction:
1383 - Inference rules are used to compile sources in subdirectories when
1384 the `subdir-objects' option is used and no per-target flags are
1385 used. This should reduce the size of some projects a lot, because
1386 Automake used to output an explicit rule for each such object in
1389 - Automake no longer outputs three rules (.o, .obj, .lo) for each
1390 object that must be built with explicit rules. It just outputs
1391 the rules required to build the kind of object considered: either
1392 the two .o and .obj rules for usual objects, or the .lo rule for
1395 * Change to Libtool support:
1397 - Libtool tags are used with libtool versions that support them.
1398 (I.e., with Libtool 1.5 or greater.)
1400 - Automake is now able to handle setups where a libtool library is
1401 conditionally installed in different directories, as in
1404 lib_LTLIBRARIES = liba.la
1406 pkglib_LTLIBRARIES = liba.la
1408 liba_la_SOURCES = ...
1410 * Changes to aclocal:
1412 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
1413 really evaluated, before it decides to include them in aclocal.m4.
1414 This solves nasty problems with conditional redefinitions of
1415 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
1416 *.m4 files to be included in any project using these macros.
1417 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
1418 most famous instance of this bug.)
1420 - Do not complain about missing conditionally AC_REQUIREd macros
1421 that are not actually used. In 1.8.x aclocal would correctly
1422 determine which of these macros were really needed (and include
1423 only these in the package); unfortunately it would also require
1424 all of them to be present in order to run. This created
1425 situations were aclocal would not work on a tarball distributing
1426 all the macros it uses. For instance running aclocal on a project
1427 containing only the subset of the Gettext macros in use by the
1428 project did not work, because gettext conditionally requires other
1431 * Portability improvements:
1433 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
1434 tar-pax. The new option filename-length-max=99 helps diagnosing
1435 filenames that are too long for tar-v7. (PR/414)
1437 - Variables aumented with `+=' are now automatically flattened (i.e.,
1438 trailing backslashes removed) and then wrapped around 80 colummns
1439 (adding trailing backslashes). In previous versions, a long series
1445 would result in a single-line definition of VAR that could possibly
1446 exceed the maximum line length of some make implementations.
1448 Non-augmented variables are still output as they are defined in
1453 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
1454 Works the same as the old Fortran 77 implementation; just replace
1455 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
1456 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
1458 - Support for conditional _LISP.
1460 - Support for conditional -hook and -local rules (PR/428).
1462 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
1464 - Automake will not write any Makefile.ins after the first error it
1465 encounters. The previous Makefile.ins (if any) will be left in
1466 place. (Warnings will not prevent output, but remember they can
1467 be turned into errors with -Werror.)
1469 - The restriction that SUBDIRS must contain direct children is gone.
1472 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
1473 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
1475 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1477 Bugs fixed in 1.8.5:
1479 * Long-standing bugs:
1481 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
1482 so that `make distclean' and `make maintainer-clean' can work.
1484 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
1486 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
1488 - Polish diagnostic when no input file is found.
1490 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1492 Bugs fixed in 1.8.4:
1494 * Long-standing bugs:
1496 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
1497 overridden by the user.
1499 - Honor PATH_SEPARATOR in various places of the Automake package, for
1502 - Adjust dependency tracking mode detection to ICC 8.0's new output.
1505 - Fix install-sh so it can install the `mv' binary... using `mv'.
1507 - Fix tru64 dependency tracking for libtool objects.
1509 - Work around Exuberant Ctags when creating a TAGS files in a directory
1510 without files to scan but with subdirectories to include.
1512 * Bugs introduced by 1.8:
1514 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
1515 not defined in the same conditions as the _LDADD that uses it.
1517 - Do not warn when JAVAROOT is overridden, this is legitimate.
1519 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1521 Bugs fixed in 1.8.3:
1523 * Long-standing bugs:
1525 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
1526 or any of the other *dir variables contain a space.
1528 Please note that Automake does not and cannot support spaces in
1529 filenames that are involved during the build. This change affects
1530 only installation paths, so that `make install' does not bomb out
1531 in packages configured with
1532 ./configure --prefix '/c/Program Files'
1534 - Fix the depfiles output so it works with GNU sed (<4.1) even when
1535 POSIXLY_CORRECT is set.
1537 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
1538 since Autoconf 2.54, which defines LIBOBJS itself.
1540 - Fix a potential (but unlikely) race condition in parallel elisp
1541 builds. (Introduced in 1.7.3.)
1543 - Do not assume that users override _DEPENDENCIES in all conditions
1544 where Automake will try to define them.
1546 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
1547 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
1550 This fix also affects the $(mkdir_p) variable defined since
1551 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
1552 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
1554 - Secure temporary directory creation in `make distcheck'. (PR/413)
1556 - Do not generate two build rules for `parser.h' when the
1557 parser appears in two different conditionals.
1559 - Work around a Solaris 8 /bin/sh bug in the test for dependency
1560 checking. Usually ./configure will not pick this shell; so this
1561 fix only helps cases where the shell is forced to /bin/sh.
1563 * Bugs introduced by 1.8:
1565 - In some situations (hand-written `m4_include's), aclocal would
1566 call the `File::Spec->rel2abs' method, which was only introduced
1567 in Perl 5.6. This new version reestablish support Perl 5.005.
1569 It is likely that the next major Automake releases will require at
1570 least Perl 5.6. Consider upgrading your development environment
1571 if you are still using the five-year-old Perl 5.005.
1573 - Automake would sometimes fail to define rules for targets listed
1574 in variables defined in multiple conditions. For instance on
1580 it would define only the `a.$(OBJEXT): a.c' rule and omit the
1581 `b.$(OBJEXT): b.c' rule.
1583 * New sections in manual:
1585 - Third-Party Makefiles: how to interface third party Makefiles.
1586 - Upgrading: upgrading packages to newer Automake versions.
1587 - Multiple Outputs: handling tools that produce many outputs.
1589 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1593 * A (well known) portability bug slipped in the changes made to
1594 install-sh in Automake 1.8.1. The broken install-sh would refuse to
1595 install anything on Tru64.
1597 * Fix install rules for conditionally built python files. (This never
1600 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1604 * Bugs introduced by 1.8:
1606 - Fix Config.pm import error with old Perl versions (at least
1607 5.005_03). One symptom is that aclocal could not find its macro
1610 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
1611 created by `make install' are always world readable, even if the
1612 installer happens to have an overly restrictive umask (e.g. 077).
1613 This was a mistake and has been reverted. There are at least two
1614 reasons why we must not use `-m 0755':
1615 - it causes special bits like SGID to be ignored,
1616 - it may be too restrictive (some setups expect 775 directories).
1618 - Fix aclocal to honor definitions located in files which have been
1619 m4_included manually. aclocal 1.8 had been updated to check
1620 m4_included files for new requirements, but forgot that these
1621 m4_included files can also provide new definitions.
1623 Note that if you have such a setup, we recommend you get rid of
1624 it. In the past, there was a reason to m4_include files manually:
1625 aclocal used to duplicate entire M4 files into aclocal.m4, even
1626 files that were distributed. Some packages were therefore
1627 m4_including the distributed file directly, and playing some
1628 tricks to ensure aclocal would not copy that file to aclocal.m4,
1629 in order to limit the amount of duplication. Since aclocal 1.8.x
1630 will precisely output m4_includes for local M4 files, we recommend
1631 that you clean up your setup, removing all manual m4_includes and
1632 letting aclocal output them.
1634 - Output detailed menus in the Info version if the Automake manual,
1635 so that Emacs can locate the indexes.
1637 - configure.ac and configure were listed twice in DIST_COMMON (an
1638 internal variable where Automake lists configury files to
1639 distribute). This was harmless, but unaesthetic.
1641 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
1642 This was an issue only in the Automake package itself, not in
1645 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
1646 DEST:SRC. This was wrong, as some packages do
1647 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
1650 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
1651 argument. This caused two kinds of failures:
1652 - Rules installing data in a conditionally defined directory
1653 failed when that directory was undefined. In this case no
1654 argument was supplied.
1655 - `make installdirs' failed, because several directories were
1656 passed to $(mkdir_p). This was an issue only on platform
1657 were $(mkdir_p) is implemented with `install-sh -d'.
1658 $(mkdir_p) as been changed to accept 0 or more arguments, as
1661 * Long-standing bugs:
1663 - Fix an unexpected diagnostic occurring when users attempt
1664 to override some internal variables that Automake appends to.
1666 - aclocal now scans configure.ac for macro definitions (PR/319).
1668 - Fix a portability issue with OSF1/Tru64 Make. If a directory
1669 distributes files which are outside itself (this usually occurs
1670 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
1671 from a parent package), then `make distcheck' fails due to an
1672 optimization performed by OSF1/Tru64 Make in its VPATH handling.
1673 (tests/subpkg2.test failure)
1675 - Fix another portability issue with Sun and OSF1/Tru64 Make.
1676 In a VPATH-build configuration, `make install' would install
1677 nobase_ files to wrong locations.
1679 - Fix a Perl `uninitialized value' diagnostic occurring when
1680 automake complains that a Texinfo file does not have a
1681 @setfilename statement.
1683 - Erase config.status.lineno during `make distclean'. This file
1684 can be created by config.status. Automake already knew about
1685 configure.lineno, but forgot config.status.lineno.
1687 - Distribute all files, even those which are built and installed
1688 conditionally. This change affects files listed in conditionally
1689 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
1690 as well as those listed in conditionally defined dist_*_DATA,
1691 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
1693 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
1694 doesn't conform to POSIX.
1696 - Normalize help strings for configure variables and options added
1701 - Check for python2.4 in AM_PATH_PYTHON.
1703 * Spurious failures in test suite:
1705 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
1706 tests/ltconv.test: fix failures with CVS Libtool.
1707 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
1708 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
1709 fix failures with old Texinfo versions.
1711 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1717 - The NEWS file is more verbose.
1721 - Autoconf 2.58 or greater is required.
1725 - Default source file names in the absence of a _SOURCES declaration
1726 are made by removing any target extension before appending `.c', so
1727 to make the libtool module `foo.la' from `foo.c', you only need to
1730 lib_LTLIBRARIES = foo.la
1731 foo_la_LDFLAGS = -module
1733 For backward compatibility, foo_la.c will be used instead of
1734 foo.c if this file exists or is the explicit target of a rule.
1735 However -Wobsolete will warn about this deprecated naming.
1737 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1738 of being hard-coded in each $(AR) invocation, so they can be
1739 substituted from configure.ac. This has been requested by people
1740 dealing with non-POSIX ar implementations.
1742 - New warning option: -Woverride. This will warn about any user
1743 target or variable definitions which override Automake
1746 - Texinfo rules back up and restore info files when makeinfo fails.
1748 - Texinfo rules now support the `html' target.
1749 Running this requires Texinfo 4.0 or greater.
1751 `html' is a new recursive target, so if your package mixes
1752 hand-crafted `Makefile.in's with Automake-generated
1753 `Makefile.in's, you should adjust the former to support (or
1754 ignore) this target so that `make html' recurses successfully. If
1755 you had a custom `html' rule in your `Makefile.am', it's better to
1756 rename it as `html-local', otherwise your rule will override
1757 Automake's new rule (you can check that by running `automake
1758 -Woverride') and that will stop the recursion to subdirectories.
1760 Last but not least, this `html' rule is declared PHONY, even when
1761 overridden. Fortunately, it appears that few packages use a
1762 non-PHONY `html' rule.
1764 - Any file which is m4_included from configure.ac will appear as a
1765 configure and Makefile.in dependency, and will be automatically
1768 - The rules for rebuilding Makefiles and Makefile.ins will now
1769 rebuild all Makefiles and all Makefile.ins at once when one of
1770 configure's dependencies has changed. This is considerably faster
1771 than previous implementations, where config.status and automake
1772 were run separately in each directory (this still happens when you
1773 change a Makefile.am locally, without touching configure.ac or
1774 friends). Doing this also solves a longstanding issue: these
1775 rebuild rules failed to work when adding new directories to the
1776 tree, forcing you to run automake manually.
1778 - For similar reasons, the rules to rebuild configure,
1779 config.status, and aclocal.m4 are now defined in all directories.
1780 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1781 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1782 should better define them in all directories. This is easily done
1783 using an AC_SUBST (make sure you prefix these dependencies with
1784 $(top_srcdir) since this variable will appear at different
1785 levels of the build tree).
1787 - aclocal will now use `m4_include' instead of copying local m4
1788 files into aclocal.m4. (Local m4 files are those you ship with
1789 your project, other files will be copied as usual.)
1791 Because m4_included files are automatically distributed, it means
1792 for most projects there is no point in EXTRA_DISTing the list of
1793 m4 files which are used. (You can probably get rid of
1794 m4/Makefile.am if you had one.)
1796 - aclocal will avoid touching aclocal.m4 when possible, so that
1797 Autom4te's cache isn't needlessly invalidated. This behavior can
1798 be switched off with the new `--force' option.
1800 - aclocal now uses Autoconf's --trace to detect macros which are
1801 actually used and will no longer include unused macros simply
1802 because they where mentioned. This was often the case for macros
1803 called conditionally.
1805 - New options no-dist and no-dist-gzip.
1807 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1808 py-compile, and ylwrap, now all understand --version and --help.
1810 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1811 links as part of the distclean target and including source files in
1814 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1815 argument. The latter can be used to override the default behavior
1816 (which is to abort).
1818 - Automake will exit with $? = 63 on version mismatch. (So does
1819 Autoconf 2.58) missing knows this, and in this case it will
1820 emulate the tools as if they were absent. Because older versions
1821 of Automake and Autoconf did not use this exit code, this change
1822 will only be useful in projects generated with future versions of
1825 - When using AC_CONFIG_FILES with multiple input files, Automake
1826 generates the first ".in" input file for which a ".am" exists.
1827 (Former versions would try to use only the first input file.)
1829 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1830 idiom to disable byte-compilation of lisp_LISP files, it is
1831 recommended that you switch to using lisp_DATA. Note that
1832 this is not strictly equivalent: lisp_DATA will install elisp
1833 files even if emacs is not installed, while *_LISP do not
1834 install anything unless emacs is found.
1836 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1837 available. This selection is achieved through the Makefile
1838 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1839 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1840 `$(install_sh) -m 0755 -d'.
1844 - Because `mkdir -p' is available on most platforms, and we can use
1845 `install-sh -d' when it is not, the use of the mkinstalldirs
1846 script is being phased out. `automake --add-missing' no longer
1847 installs it, and if you remove mkinstalldirs from your package,
1848 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1850 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1851 gettextize and autopoint will install it when needed. Automake
1852 will continue to define the $(mkinstalldirs) and to distribute
1853 mkinstalldirs when this script is in the source tree.
1855 - AM_PROG_CC_STDC is now empty. The content of this macro was
1856 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1857 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1858 renaming should be safe, even if you have to support several,
1859 versions of Automake, because AC_PROG_CC defines this variable
1860 since Autoconf 2.54.)
1862 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1863 variable to override the aclocal.m4 dependencies computed
1864 (inaccurately) by older versions of Automake. Because Automake
1865 now tracks configure's m4 dependencies accurately (see m4_include
1866 above), the use of ACLOCAL_M4_SOURCES should be considered
1867 obsolete and will be flagged as such when running `automake
1872 - Defining programs conditionally using Automake conditionals no
1873 longer leads to a combinatorial explosion. The following
1874 construct used to be troublesome when used with dozens of
1889 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1891 - Due to implementation constraints, previous versions of Automake
1892 proscribed multiple conditional definitions of some variables
1902 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1903 This restriction has been lifted, and these variables now
1904 support multiple conditional definitions as do other variables.
1906 - Cleanup the definitions of $(distdir) and $(top_distdir).
1907 $(top_distdir) now points to the root of the distribution
1908 directory created during `make dist', as it did in Automake 1.4,
1909 not to the root of the build tree as it did in intervening
1910 versions. Furthermore these two variables are now only defined in
1911 the top level Makefile, and passed to sub-directories when running
1914 - The --no-force option now correctly checks the Makefile.in's
1915 dependencies before deciding not to update it.
1917 - Do not assume that make files are called Makefile in cleaning rules.
1919 - Update .info files in the source tree, not in the build tree. This
1920 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1921 used to update these files in the build tree (previous versions did
1922 it in the source tree too), and it caused several problems, varying
1923 from mere annoyance to portability issues.
1925 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1926 when --add-missing and --force-missing are used. For backward
1927 compatibility --add-missing will continue to install COPYING (in
1928 `gnu' strictness) when none of these three files exist, but this
1929 use is deprecated: you should better choose a license yourself and
1930 install it once for all in your source tree (and in your code
1933 - Fix ylwrap so that it does not overwrite header files that haven't
1934 changed, as the inline rule already does.
1936 - User-defined rules override automake-defined rules for the same
1937 targets, even when rules do not have commands. This is not new
1938 (and was documented), however some of the automake-generated
1939 rules have escaped this principle in former Automake versions.
1940 Rules for the following targets are affected by this fix:
1942 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1943 info, info-am, install-data-am, install-exec-am, install-info,
1944 install-info-am, install-man, installcheck-am, maintainer-clean,
1945 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1946 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1948 Practically it means that an attempt to supplement the dependencies
1949 of some target, as in
1951 clean: my-clean-rule
1953 will now *silently override* the automake definition of the
1954 rule for this target. Running `automake -Woverride' will diagnose
1955 all such overriding definitions.
1957 It should be noted that almost all of these targets support a *-local
1958 variant that is meant to supplement the automake-defined rule
1959 (See node `Extending' in the manual). The above rule should
1962 clean-local: my-clean-rule
1964 These *-local targets have been documented since at least
1965 Automake 1.2, so you should not fear the change if you have
1966 to support multiple automake versions.
1970 - The Automake manual is now distributed under the terms of the GNU FDL.
1972 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1974 - core dumps are no longer removed by the cleaning rules. There are
1975 at least three reasons for this:
1976 1. These files should not be created by any build step,
1977 so their removal do not fit any of the cleaning rules.
1978 Actually, they may be precious to the developer.
1979 2. If such file is created during a build, then it's clearly a
1980 bug Automake should not hide. Not removing the file will
1981 cause `make distcheck' to complain about its presence.
1982 3. Operating systems have different naming conventions for
1983 core dump files. A core file on one system might be a
1984 completely legitimate data file on another system.
1986 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1987 defined by Automake. This means that any definition in the
1988 environment will be used, unless overridden in the Makefile.am or
1989 on the command line. The old behavior, where these variables were
1990 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1991 AC_ARG_VARing each variable from configure.ac.
1993 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1994 documented. (The is not a new feature, these variables have
1995 been there since at least Automake 1.4.)
1997 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

2000 * Fix install-strip to work with nobase_ binaries.
2001 * Fix renaming of #line directives in ylwrap.
2002 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)

2005 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
2006 * Fix detection of Debian's install-info, broken since version 1.5.
2007 (Debian bug #213524).

2009 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
2011 Bugs fixed in 1.7.7:
2012 * The implementation of automake's --no-force option is unreliable,
2013 so this option is ignored in this version. A real fix will appear in
2014 Automake 1.8. (Debian Bug #206299)
2015 * AM_PATH_PYTHON: really check the whole list of interpreters if no
2016 argument is given. (PR/399)
2017 * Do not warn about leading `_' in variable names, even with -Wportability.
2018 * Support user redefinitions of TEXINFO_TEX.
2019 * depcomp: support AIX Compiler version 6.
2020 * Fix missing rebuilds during `make dist' with BSD make.
2021 (Could produce tarballs containing out-of-date files.)
2022 * Resurrect multilib support.
2023 * Noteworthy manual updates:
2024 - Extending aclocal: how to write m4 macros that won't trigger warnings
2026 - A Shared Library: Rewrite and split into subsections.
2028 Bugs fixed in 1.7.6:
2029 * Fix depcomp's icc mode for ICC 7.1.
2030 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
2031 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
2032 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
2033 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
2034 * Remove Latin-1 characters from elisp-comp.
2035 * Update the manual's @dircategory to match the Free Software Directory.
2037 Bugs fixed in 1.7.5:
2038 * Update install-sh's license to remove an advertising clause.
2039 (Debian bug #191717)
2040 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
2041 that caused invalid Makefile.ins to be generated.
2042 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
2043 * New FAQ entry: renamed objects.
2045 Bugs fixed in 1.7.4:
2046 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
2047 the Emacs implementation)
2048 * Fix output of aclocal.m4 dependencies in subdirectories.
2049 * Use `mv -f' instead of `mv' in fastdep rules.
2050 * Upgrade mdate-sh to work on OS/2.

2059 * Minor documentation fixes.
2061 Bugs fixed in 1.7.3:
2062 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
2063 * Query distutils for `pythondir' and `pythonexecdir', instead of
2064 using an hardcoded path. This should allow builds on 64-bit
2065 distributions that usually use lib64/ instead of lib/.
2066 * AM_PATH_PYTHON will also search for python2.3.
2067 * elisp files are now built all at once instead of one by one. Besides
2068 incurring a speed-up, this is required to support interdependent elisp files.
2069 * Support for DJGPP:
2070 - `make distcheck' will now work in `_inst/' and `_build' instead
2071 of `=inst/' and `=build/'
2072 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
2073 - install/uninstall `*.i[0-9][0-9]'-style info files
2074 - more changes that affect only the Automake package (not its output)
2075 * Fix some incompatibilities with upcoming perl-5.10.
2076 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
2077 PACKAGE and VERSION.
2079 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
2080 is troublesome with gcc and Solaris compilers. (PR/385)
2081 - makedepend mode: work with Libtool. (PR/385 too)
2083 * better support for unusual gettext setups, such as multiple po/ directories
2085 - Flag missing po/ and intl/ directories as warnings, not errors.
2086 - Disable these warnings if po/ does not exist.
2087 * Noteworthy manual updates:
2089 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
2091 - Document `AM_YFLAGS = -d'. (PR/382)
2093 Bugs fixed in 1.7.2:
2094 * Fix installation and uninstallation of Info files built in subdirectories.
2095 * Do not run `./configure --with-included-gettext' during `make distcheck'
2096 if AM_GNU_GETTEXT([external]) is used.
2097 * Correctly uninstall renamed man pages.
2098 * Do not strip escaped newline in variables defined in one condition
2099 and augmented in another condition.
2100 * Fix ansi2knr rules for LIBOBJS sources.
2101 * Clean all known Texinfo index files, not only those which appear to
2102 be used, because we cannot know which indexes are used in included files.
2103 (PR/375, Debian Bug #168671)
2104 * Honor only the first @setfilename seen in a Texinfo file.
2105 * Treat "required file X not found" diagnostics as errors (exit status 1).
2106 * Don't complain that a required file is not found when it is a Makefile
2108 * Don't use single suffix inference rules when building `.info'-less
2109 Info files, for the sake of Solaris make.
2110 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
2111 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
2112 * Warn about multiple inference rules when -Wportability is used. (PR/372)
2113 * Fix building of deansified files from subdirectories. (PR/370)
2114 * Add missing `fi' in the .c->.obj rules.
2115 * Improve install-sh to work even when names contain spaces or certain
2116 (but not all) shell metachars.
2117 * Fix the following spurious failures in the test suite:
2118 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
2119 * Noteworthy manual updates:
2120 - Augment the section about BUILT_SOURCES.
2121 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
2123 Bugs fixed in 1.7.1:
2124 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
2126 * Aclocal should now recognize macro names containing parentheses, e.g.
2127 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
2128 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
2130 * Install Python files even if they were built. (PR/369)
2131 * Have stamp-vti dependent upon configure instead of configure.ac, as the
2132 version might not be defined in the latter. (PR/358)
2133 * Reorder arguments passed to a couple of commands, so things works
2134 when POSIXLY_CORRECT=1.
2135 * Fix a regex that can cause Perl to segfault on large input.
2137 * Fix distribution of packages that have some sources defined conditionally,
2138 as in the `Conditional compilation using Automake conditionals' example
2140 * Fix spurious test suite failures on IRIX.
2141 * Don't report a required variable as undefined if it has been
2142 defined conditionally for the "right" conditions.
2143 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
2144 `make distcheck' fails.
2145 * Fix distribution of included Makefile fragment, so we don't create
2146 spurious directories in the distribution. (PR/366)
2147 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
2150 * Autoconf 2.54 is required.
2151 * `aclocal' and `automake' will no longer warn about obsolete
2152 configure macros. This is done by `autoconf -Wobsolete'.
2153 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
2154 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
2155 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
2156 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
2157 `configure.ac' for you.
2158 * Support for per-program and per-library `_CPPFLAGS'.
2159 * New `ctags' target (builds CTAGS files).
2160 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
2161 (see `automake --help' or the manual for a list of them).
2162 * Honor the WARNINGS environment variable.
2163 * Omit the call to depcomp when using gcc3: call the compiler directly.
2164 * A new option, std-options, tests that programs support --help and --version
2165 when `make installcheck' is run. This is enabled by --gnits.
2166 * Texinfo rules now support the `ps' and `pdf' targets.
2167 * Info files are now created in the build directory, not the source directory.
2168 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
2170 * `make distcheck' will enforce DESTDIR support by attempting
2172 * `+=' can be used in conditionals, even if the augmented variable
2173 was defined for another condition.
2174 * Makefile fragments (inserted with `include') are always distributed.
2175 * Use Autoconf's --trace interface to inspect configure.ac and get
2176 a more accurate view of it.
2177 * Add support for extending aclocal's default macro search path
2178 using a `dirlist' file within the aclocal directory.
2179 * automake --output-dir is deprecated.
2180 * The part of the distcheck target that checks whether uninstall actually
2181 removes all installed files has been moved in a separate target,
2182 distuninstallcheck, so it can be overridden easily.
2186 * Support for AM_INIT_GETTEXT([external])
2187 * Bug fixes, including:
2188 - Fix Automake's own `make install' so it works even if `ln' doesn't.
2189 - nobase_ programs and scripts honor --program-transform correctly.
2190 - Erase configure.lineno during `make distclean'.
2191 - Erase YACC and LEX outputs during `make maintainer-clean'.
2194 * Many bug fixes, including:
2195 - Requiring the current version works.
2196 - Fix "$@" portability issues (for Zsh).
2197 - Fix output of dummy dependency files in presence of post-processed
2199 - Don't compute dependencies in background to avoid races with libtool.
2200 - Fix handling of _OBJECTS variables for targets sharing source variables.
2201 - Check dependency mode for Java when AM_PROG_GCJ is used.
2204 * automake --output-dir is deprecated
2205 * Many bug fixes, including:
2206 - Don't choke on AM_LDFLAGS definitions.
2207 - Clean libtool objects from subdirectories.
2208 - Allow configure variables with reserved suffix and unknown prefix
2209 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
2210 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
2213 * Autoconf 2.52 is required.
2214 * automake no longer run libtoolize.
2215 This is the job of autoreconf (from GNU Autoconf).
2216 * `dist' generates all the archive flavors, as did `dist-all'.
2217 * `dist-gzip' generates the Gzip tar file only.
2218 * Combining Automake Makefile conditionals no longer lead to a combinatorial
2219 explosion. Makefile.in's keep a reasonable size.
2220 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
2221 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
2223 * `#line' of Lex and Yacc files are properly set.
2224 * EXTRA_DIST can contain generated directories.
2225 * Support for dot-less extensions in suffix rules.
2226 * The part of the distcheck target that checks whether distclean actually
2227 cleans all built files has been moved in a separate target, distcleancheck,
2228 so it can be overridden easily.
2229 * `make distcheck' will pass additional options defined in
2230 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
2231 * Fixed CDPATH portability problems, in particular for MacOS X.
2232 * Fixed handling of nobase_ targets.
2233 * Fixed support of implicit rules leading to .lo objects.
2234 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
2235 * Added uninstall-hook target
2236 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
2237 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
2238 (Note that "pkgname" is not "tarname", see the manual for details.)
2239 It is also possible to pass a list of global Automake options as
2240 first argument to this new form of AM_INIT_AUTOMAKE.
2241 * Compiler-based assembler is now called `CCAS'; people expected `AS'
2242 to be a real assembler.
2243 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
2244 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
2245 * aclocal and automake are also installed with the version number
2246 appended, and some of the install directory names have changed.
2247 This lets you have multiple versions installed simultaneously.
2248 * Support for parsers and lexers in subdirectories.
2251 * Support for `configure.ac'.
2252 * Support for `else COND', `endif COND' and negated conditions `!COND'.

2272 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
2273 * Support for latest autoconf, including support for objext
2274 * Can now put `.' in SUBDIRS to control build order
2275 * `include' command and `+=' support for macro assignment
2276 * Dependency tracking no long susceptible to deleted header file problem

2282 * Better Cygwin32 support
2283 * Support for suffix rules with _SOURCES variables
2284 * New options `readme-alpha' and `check-news'; Gnits mode sets these

2307 * Better C++, yacc, lex support
2308 * Will compute _DEPENDENCIES variables automatically if not supplied
2309 * Will interpolate $(...) and ${...} when examining contents of a variable
2310 * .deps files now in build directory, not source directory; dependency

2317 * configure substitutions are automatically discovered and included
2318 in generated Makefile.in
2319 * Special --cygnus mode
